Ans 1.  Yes, it's possible when the acceleration and velocity both are in the negative direction.
 In this case, let the acceleration be towards the negative x-axis and the the velocity also in the same direction. In that case the speed will increase.

Ans 2. In this case, assume the velocity and acceleration to be in the opposite directions. I mean to say assume that the acceleration of the body is in positive x-direction and let the initial velocity of the particle be in negative x-direction. In this case, the particle will momentarily come to rest first and then will ultimately begin to move in the opposite direction, thus changing its direction of motion with an increasing speed.



 Hope it helps!!!
 If you have any doubts, then you may ask!!!
